The University of Tokyo【Background】 Sexual and reproductive health (SRH) is an important public health concern foryouths. They have scarce opportunities for comprehensive sexuality education (CSE) in non-school
settings, particularly for those who drop out of school. Film is growingly accessible for youths using
their mobile devices and social media. This study was conducted to investigate the immediate effectof providing SRH information via film on youth’s self-efficacy in seeking SRH information inCambodia. It was also conducted to evaluate intervention acceptability via the level of helpfulness
and likeliness to recommend the intervention.
【Methods】 As a randomized controlled trial, this study provided SRH information including SRH
rights, modern contraceptive methods, and access to youth-friendly services via a short film
intervention. Participants were Cambodian youths aged between 18 and 24 living in Cambodia.
They were recruited via social media platforms such as Facebook. The youths were randomly
allocated to either watch SRH information via film in the intervention arm or read it as text in thecontrol arm. A 7-item 5-point Likert scale measured self-efficacy in seeking SRH information. The
assessment was made immediately after the intervention. The mixed effect generalized linear model
was used to estimate the immediate effect of the intervention on self-efficacy. The generalized
linear model was used to estimate the effect on acceptability.
【Results】 The intervention was conducted from October 21, 2022, to December 1, 2022. A totalof 241 youths were recruited into the study. After the allocation, 54 youths were excluded for not
meeting the inclusion criteria, and two youths declined to participate. The study included 185
youths (intervention = 87, control = 98). The mean self-efficacy scores increased from 4.31 to 4.40
in the intervention arm and from 4.26 to 4.34 in the control arm (B = 0.01, 95% CI -0.10 to 0.13).
Among youths with sexual experiences, the mean self-efficacy score increased by 0.16 points (from4.44 to 4.60) in the intervention arm and by 0.05 points (from 4.32 to 4.37) in the control arm.
The acceptability of the contents differed between the intervention and control arms, regarding thepercentage of perceiving the content was helpful (89.7% vs. 81.6%; AOR = 1.51, 95% CI 0.60 to3.79) and recommending the contents (87.3% vs. 66.3%; AOR = 2.95, 95% CI 1.32 to 6.59). Among
those with sexual experiences, the differences were wider between the arms regarding thepercentage of perceiving the content was helpful (86.4% vs. 60.5%) and recommending the contents

(86.4% vs. 44.7%).
【Conclusions】 This study did not find significant effect on improving youths’ level of SRH
information-seeking self-efficacy by using a film-based intervention content, compared to using atext-based content. Youths from both arms reported a high level of acceptability for both contents.
The level of recommendation for the film-based intervention was significantly higher than the textbased content. Youths with sexual experience were more likely to find the film intervention helpful
and recommend the contents.
